This is React Native Bluetooth Low Energy library using RxBluetoothKit and RxAndroidBle under the hood.

It supports:

• observing device's Bluetooth adapter state
• scanning BLE devices
• making connections to peripherals
• discovering services/characteristics
• reading/writing characteristics
• observing characteristic notifications/indications
• reading RSSI
• negotiating MTU
• background mode on iOS
• turning the device's Bluetooth adapter on

What this library does NOT support:

• communicating between phones using BLE (Peripheral support)
• bonding peripherals

¹ fails on Android, although might work after updating gradle

² may require usage of jetifier on Android and migration to CocoaPods on iOS.

1.1.1

• Update development dependencies
• Add more information to the README and INTRO file.
• Remove const from enum types in the typescript definition file.
• Add backpressure buffer for notifications.

1. Make sure your Expo project is ejected (formerly: detached). You can read how to do it here and here. (only for expo)
2. npm install --save react-native-ble-plx
3. react-native link react-native-ble-plx
4. Open Xcode workspace located inside ios folder and add empty Swift file if you don't have at least one:
   • Select File/New/File...
   • Choose Swift file and click Next.
   • Name it however you want, select your application target and create it.
   • Accept to create Objective-C bridging header.
5. Update your ios/Podfile to contain:

   pod 'react-native-ble-plx', :path => '../node_modules/react-native-ble-plx'
   

6. Enter ios folder and run pod update
7. Minimal supported version of iOS is 8.0
8. If you want to support background mode:
   • In your application target go to Capabilities tab and enable Uses Bluetooth LE Accessories in Background Modes section.
   • Pass restoreStateIdentifier and restoreStateFunction to BleManager constructor.
9. Starting from iOS 13 add NSBluetoothAlwaysUsageDescription in info.plist file.

1. npm install --save react-native-ble-plx

2. react-native link react-native-ble-plx

3. Open Xcode project located inside ios folder and add empty Swift file if you don't have at least one:

   • Select File/New/File...
   • Choose Swift file and click Next.
   • Name it however you want, select your targets and create it.
   • Accept to create Objective-C bridging header.

4. Minimal supported version of iOS is 8.0

5. If you want to support background mode:

   • In your application target go to Capabilities tab and enable Uses Bluetooth LE Accessories in Background Modes section.
   • Pass restoreStateIdentifier and restoreStateFunction to BleManager constructor.

6. Starting from iOS 13 add NSBluetoothAlwaysUsageDescription in info.plist file.

1. npm install --save react-native-ble-plx
2. react-native link react-native-ble-plx
3. In build.gradle of app module make sure that min SDK version is at least 18:

android {
    ...
    defaultConfig {
        minSdkVersion 18
        ...

4. In build.gradle of app module make sure to add jitpack repository to known repositories:

allprojects {
    repositories {
      ...
      maven { url 'https://jitpack.io' }
    }
}

5. In AndroidManifest.xml, add Bluetooth permissions and update <uses-sdk/>:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    ...
    <uses-permission android:name="android.permission.BLUETOOTH"/>
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
    <uses-permission-sdk-23 android:name="android.permission.ACCESS_COARSE_LOCATION"/>

    <!-- Add this line if your application always requires BLE. More info can be found on:
         https://developer.android.com/guide/topics/connectivity/bluetooth-le.html#permissions
      -->
    <uses-feature android:name="android.hardware.bluetooth_le" android:required="true"/>

    <uses-sdk
        android:minSdkVersion="18"
        ...

6. If you are using AndroidX, then for the time being you need to convert import statements in the Android library with jetifier. These steps apply for all react-native packages, which are during the transition period:

• npm install --save-dev jetifier
• Run jetify script after npm install. You can do it by adding "postinstall" script to the package.json file:

   ...
   "postinstall": "npx jetify",
   ...

Add this to your app/proguard-rules.pro
